IMPROVEMENT IN LOOlVlS.

Specification forming part of Letters Patent No. 52,192, dated January 23, 1866; antedated January 17, 1866.

To all whom it may concern Be it known that I, BENJAMIN OLDFIELD, of 'Williamsburg, Kings county, State of New York, have invented a new and useful Improvementin Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein g had to theaccompanyin g drawings, forming part of this specification, in Which- Figure l represents a front elevation of this invention. Fig. 2 is a plan or top view of the same. Fig. 3 is a transverse vertical section ofthe same, thelinexzr, Fig. 2, indicating the 'plane ot' section, the shuttles B B being placed in the shed ot' the warp and shown in cross-sectiou, and the shuttle F in end view.

Similar letters or" reference indicate like parts.

This invention relates particularly to looms for weaving figured goods; and it consists in the arrangement ot' two or more shuttles for carrying the weft for forming the plain portion ofthe fabric, and one or more shuttles for carrying the weft used in forming the figured part of the same, in such a manner that the shuttles which form the plain part are driven simultaneously through the same opening in the warp or shed, and the iiguring shuttle or shuttles are moved at such intervals as the pattern may require, and that by driving two or more shuttles for the plain weaving simultaneously through the same opening much time is saved, and stronger and heavier goods can be produced at less expense than on looms ot' the ordinary construction.

A represents the batteri, which is provided in its breast with two or more grooves to form the guides c c for the shuttles B B. These shuttles work one above the other, and they are provided with quills b b' and tensionspriugs c c', ofwell-known construction. They discharge their threads through eyes c e', (see Figs. l and 3,) and motion is imparted to them by means of toothed racks C C', which slide in a suitable groove in the bottom part ofthe batteu, and which gear into cog-wheels D D', as shown particulary in Figs. 1 and 3. Two

cog-wheels are required for each shuttle, one on either side of the space E, and they gear into suitable cogs in the under sides of the shuttles. Said cog-wheels are so situated that one of them is always in gear with its shuttle, and when the shuttle passes the space it comes in gear with the cog-wheel on the opposite side thereof before it comes out of gear with the wheel which had propelled it up to the space. Two or more shuttles may be thus arranged, one above the other, and they pass simultaneously through the same opening or shed of the warp, so that for each motion twice as much material is introduced as is used by looms ot' the ordinary construction, and strong and heavy goods can be produced in a comparatively short time.

The shuttles B B' operate in conjunction with the shuttle F, which carries the material for iiguringther'abric. This shuttle is guided in a groove in the top edge ofthe hatten, and it is propelled by a toothed rack, Gr, and cogwheels H, in the same manner as the shuttles B B', though it must be remarked that other motions may be employed to propel the shutt-les, and I do not wish to continc myself to the precise means shown in the drawings, but reserve the right to change the same as may be desirable.

It is obvious that instead of one figuringshuttle two or more such shuttles may be employed. This shuttle is driven through the opening or shed of the warp at such intervals as the pattern may require, and the iiguring is produced by the weft, so that every thread shows, and but a small part of the material used for figuring is covered up or concealed by the material used for producing the plain parts ot' the fabric. The motion ot' the iiguring shuttle or shuttles alternates with that ot' the shuttles for plain weaving, and the shed for the guring shuttle or shuttles is produced by other portions of the harness than those which produce the shed for the shuttles for plain weaving, according to the pattern desired.
